Title: Refractive wave muffler
Inventor: ASHER RODNEY LEE
IPC: F01N1/00
Filed: 2001-11-09
Abstract: Within an exhaust duct are positioned a plurality of concentrically arranged, open ended, right cylinders supported axially within the exhaust duct, wherein each of the cylinders includes an inlet end and an exit end. The inlet ends are positioned in sequential downstream order from the outermost of the cylinders to the innermost of the cylinders. The cylinders are graduated in length sequentially with the outermost cylinder being shortest in length and the innermost cylinder being longest in length. The inlet ends of each of the cylinders provide a circular leading edge with a sawtooth conformation. An elongated smooth rod is positioned on the longitudinal axis of the exhaust duct with a downstream end of the rod providing a flared portion positioned at the mouth of the innermost of the cylinders. A plurality of radially directed flow directing vanes are engaged along their outer edge with an inside surface of the exhaust duct and also along an inside edge with each of the cylinders and the rod for securing them in place within the exhaust duct. These flow directing vanes extend upstream of the outermost of the cylinders and downstream of the innermost of the cylinders.

Patent CA-2366591-A1 (CA)
Inventor: POPOVIC BRANISLAV
IPC: H04L7/04
Filed: 2000-04-04
Abstract: For one embodiment, a Random Access Channel (RACH) preamble modulation method and apparatus are disclosed in which the real (I) and imaginary (Q) components of a complex RACH preamble (b(k)) are filtered in corresponding pulse shaping filters (206, 208).  Consequently, the phase transitions in the resulting signal are limited at all chip positions, and the resulting quadriphase codes produce transmitted signals with lower Peak-to-Average Power Ratios (PAPRs) than those that result using conventional Hybrid Phase-Shift Keying (HPSK) modulation schemes. On the other side, the resulting quadriphase synchronization code retains the same aperiodic autocorrelation magnitude as the original binary code (a(k)), optimized to produce the minimum probability of incorrect synchronization.
